This particular study investigates Erbium-substituted Ba2Co2Fe28O46 hexaferrites prepared through a meticulous heat treatment process at 1350 °C. XRD analysis unveiled X, W-type, and α-Fe2O3 phases in the x = 0.0 sample, while Er-substituted samples exhibited the presence of X and W phases. Mössbauer spectroscopy, employing five sextets, elucidated a notable variation in saturation magnetization (MS). Remarkably, the x = 0.12 composition demonstrated peak MS (52.29 Am2/kg) and anisotropy field-Ha (1370 kA/m), correlating with a maximum relative area (~69%) for spin-up sites (k+a+b).

These dielectric investigations, spanning low frequency (20 Hz–2 MHz), showcased typical ferromagnetic behavior attributed to grain boundary contributions, transitioning to grain contributions at higher frequencies. AC conductivity exhibited an increasing trend with frequency across all hexaferrite compositions. The observed soft ferrite behavior and low dielectric loss tangent in substituted compositions suggest promising applications in filter technologies.

These findings contribute to the understanding of magnetic and dielectric properties in Erbium-substituted hexaferrites, emphasizing their potential in advanced applications. Further discussions on specific applications and avenues for future research are encouraged. #MaterialsScience #Hexaferrites #MagneticProperties #DielectricCharacterization #ResearchDiscussion
